TRACTION-WHEEL.

Specification of Letters Patent.

Patented Mar. 22, 19211..

Application filed April 2, 1920. Serial No. 370,790.

T 0 all whom it may concern:

Be it known that I, WILLIAM J. TEKIPPE, a citizen of the United States, residing at New Hampton, in the county of Chickasaw and State of Iowa, have invented a new and useful Traction-WVheel, of which the following is a specification.

This invention relates to traction wheels.

The object is to provide a wheel particularly adapted for use on tractors, binders, harvesters or similar machines wherein great strength is required, and to construct the same of stock material readily found on the market, the same requiring no special castings or fittin s, and being easily set up by ordinary mec anics.

Another object is to provide a wheel of this character having a broad bearing tread equipped with traction flights and having the sides completely inclosed to exclude water, mud and trash and avoid clogging of the wheel during its course over the ground, no matter what the condition of the latter may be.

A full and complete understanding of the invention may be obtained from a consideration of the following detailed description taken in connection with the accompanying drawing forming part of this specification, with the understanding, however, that the invention is not confined to any strict conformity with the showing of the drawing, but may be changed and modified so long as such changes and modifications mark no material departure from the salientfeatures of the invention as expressed in the appended claims.

In the drawing, in which similar reference characters designate corresponding parts throughout the several figures Figure 1 is a side elevation of a wheel constructed in'accordance with the invention; Fig. 2 is a vertical central section taken at ri 'ht angles to the axis of the wheel;

Fig. 3 is a vertical sectional view taken through the wheel axis.

The wheel consists essentially in parts made, respectively, of sheetmetal, such as boiler plate or some equally strong and durable metal, angle iron reinforcements and heavy steel rod material comprising spokes, so connected and arranged as to give a maximum amount of strength with a minimum amount of weight.

While particularly adaptable to use as traction wheels for tractors, binders, harvesters, etc., as has been stated, it will be-seen that the wheel may be advantageously employed for other purposes.

an annular, fiat, sheet metal ring 1, comprisingthe tread of the wheel, is formed of a length of boiler iron or similar metal and welded or otherwise connected together at its ends to provide a ring of the desired diameter. This tread member or ring 1 is of such width as to give a broad bearing surface to prevent sinking of the wheel, when under load, into soft, plowed, or muddy ground. Head disks 2 preferably formed of boiler ron orsiinilar material, are fitted into the inner diameter of the tread ring 1, the disk being cut from a solid sheet of said metal to snugly fit into the ring, and provided at their centers with alined apertures 3. Surrounding these apertures are reinforcing disks 4 having alined apertures, and secured thereto by bolts 5, to prevent the head disks from bending or buckling while under load and to give a greater bearing at the center of the wheel. The bolts 5 extend from one head 2 to the other.

A metallic sleeve or hub 6 which is tubular in form extends between the outer faces of the reinforcing disks, and is provided with a pair of spaced annular flanges 7 each having a series of radially-disposed sockets which are suitably threaded for the reception of the inner ends of heavy steel rod spokes 8. The outer ends of the spokes 8 are fixed in countersunk seats 9 inthe annular tread ring 1, and the said spokes are preferably arranged in pairs, and are closer together at their outer ends where connected to the tread ring than they are at the center of the wheel. The outer ends of the spokes may be secured to the tread of the wheel in any well-known manner, riveting being the simplest method, as the same may be accomplished after the inner ends of the spokes have been properly screwed into the flanges 7 of the hub sleeve. The converging relation of the spokes of the several pairs tends to brace the construction and prevent any side play of the several parts.

Circular flanges 7 formed integrally with the hub 6 and arranged outside of the flanges 7,-are adapted to bear against the inner faces of the heads 2 and to receive the provided adapted to be traversed by the said bolts 5.

Annular rings 10, formed of ordinary angle iron and having the radially disposed flanges thereof abutting against the inner face of each of the head disks 2, are secured to the tread ring 1 by rivets 11, placed at intervals around the entire circumference of the tread ring. The angle rings 10 are provided in said radially disposed flanges with a series of alined openings in registering relation with similar openings formed in the head disks for the reception of elongated heavy rivets 12 extending from head to head and surrounded by spacing sleeves 13 of tubular formation. These sleeves have their ends bearing against the inner opposed faces of the radial flanges of, the angle-iron rings, and the rivets 12 have their ends headed over in a well-known manner to draw the parts together and form a rigid structure and to bind the tread portion of the wheel together. These rivets 12 are located midway between the pairs of spokes 8, as clearly shown in Figs. 1 and 2, and are arranged close to the periphery of the wheel where the strain of pulling the wheel through soft or sticky ground requires reinforcement.

Arranged at intervals around the outer periphery of the tread ring 1 is a series of transversely disposed cleats 14 formed of angle iron, or of any other desired form of metal, suitably secured as by rivets and adapted to provide good traction, the broad tread furnishing ample bearing surface for the purpose. The hub 6 is adapted to fit the reduced end portion 15 of the shaft or axle 16, which may be taken as indicative of a part of any machine upon which the improved wheel is adapted to be used. The wheel may be held in place by the usual nut 17, and may have secured to its inner head. disk 2 any suitaable formlof sprocket wheel or gear 2 to be used in connection with other gearing for driving the wheel in any well known man ner.

From the foregoing it will be seen that an extremely simple, cheaply manufactured and eflicient traction wheel has been provided, and which is built tovwithstand the great strain to which such wheels are subjected, and which will prevent the entrance therein of mud, trash or water, thus rendering the same more easily driven through soft or wet ground.

What is claimed is 1. A traction wheel comprising a sheet metal tread ring, head disks having central apertures and fitting within and lying flush with the outer edges of the tread ring, annular reinforcing rings formed of angle iron fitting within and attached to the tread ring and bearing against the inner faces of the head disks, elongated rivets traversing the head disks and the angle iron rings and arranged transversely of the wheel close to the tread ring, a hub on which the head disks are mounted, and means for connecing the spokes to the hub within the disks.

2. Atraction wheel, comprising a sheet metal tread ring having cleats around its outer periphery, head disks having central apertures and fitting within and lying flush with the outer edges of the tread ring, annular reinforcing rings formed of angle iron fitting within and attached to the tread ring and bearing against the inner faces of the head disks, elongated rivets traversing the head disks and the angle iron rings and arranged transversely of the wheel close to the tread ring, spacer sleeves mounted on the said rivets and having their ends hear.- ing against the inner opposed faces of the angle iron rings, spokes secured to the tread ring midway between the transverse rivets having the spacer sleeves, a hub extending beyond each head disk and having spaced flanges provided with radially-disposed threaded sockets for the reception of the inner ends of the spokes, andreinforcing disks mounted upon the ends of the hub and secured to the said head disks.

3. A. traction wheel comprising a sheet metal tread ring having cleats around its outer periphery, head disks having central apertures and fitting within and lying flush with the outer edges of the tread ring, annular reinforcing rings formed of angle iron fitting within and attached to the tread ring and bearing against the j inner faces of the head disks, elongated rivets traversing the head disks and the angle iron rings and arranged transversely of the wheel close to the tread ring, spacer sleeves mounted on the said rivets and having their ends bearing against the inner opposed faces of the angle iron rings, spokes secured to the tread ring, a hub fitting the apertures of the disks, and means provided on the hub for the connection of the spokes thereto.

4%. A traction wheel'comprising a sheet metal tread ring having cleats around its outer periphery, head disks having central apertures and fitting within and lying flush with the outer edges of the tread ring,--annular reinforcing rings formed of angle iron fitting within and attached to the tread ring and bearing against the inner faces of the head disks, elongated rivets traversing the head disks and the angle iron rings and arranged transversely of the wheel close to the tread ring, spacer sleeves mounted on the said rivets and having their ends bearing against the inner opposed faces of the angle iron rings, spokes secured to the tread ring, a hub fitting the apertures of the disks, and extending beyond the outer faces of the same, and having circular flanges bearing against the inner faces of the head disks, reinforcing disks mounted on the ends of the hub outside of the head disks, bolts traversing the reinforcing disks, the head disks and the said circular flanges on 10 both sides to draw the same together.

In testimony that I claim the foregoing as my own I have hereto afiixed my si nature.

WILLIAM J. TEKfPPE.
